HI Daryl,

re:

Wow!

re:
> Anyway, my question for you folks is if all your servers have
> jumbo frames (MTU=9000) enabled?

Yes all real-server backends to the current implementation of
both idd.unidata.ucar.edu and iddb.unidata.ucar.edu are
configured for jumbo frames.  The previous incarnation of
idd.unidata.ucar.edu was not.

re:

Hmm...  We'll kick this possibility around of course, but it
doesn't "feel" right.

Cheers,

Tom
